Drilling-machines ; milling - machines. - A machine for forming the grooves and holes comprises a segmental support b, Fig. 5, for the ingot 1 which rests with two of its angular faces on a pair of interchangeable shaped blocks on the support. The work, together with the support, is movable about its axis by means of a worm operated by a hand wheel b<3> and is indexed relatively to the grinding or milling disc a, to produce the two grooves, by a plunger b<4>. The support b is also movable parallel and transversely to the work axis by hand-wheels b<5>, b<6>. The grinding &c. disc a is mounted in an eccentric a<5> for imparting the cutting feed in such a manner that the disc cuts on part only of the periphery of the groove during the operative traverse, and in addition the disc may be given an axial feed so as to follow an inclined straight or curved path and cut on one only of its flanks. The disc is driven by an electric motor a<4> and is carried by a slide a<1> vertically adjustable on a bracket a<2> which is capable of horizontal adjustment in two perpendicular directions by means of a slide a<3>. When grooves 2, 3 are made in both ends of the work, milling or grinding discs may be provided at opposite sides of the work-support B, or one disc only may be used and the support made capable of rotating horizontally through 180‹.

Abstract: 1388363 Tape transports; sensing end of tape AMERICAN VIDEONETICS CORP 22 June 1973 [21 Aug 1972] 29827/73 Heading G5R [Also in Division F2] An end-of-tape sensing device includes a capstan 81 for winding up an elongate tendon 77 to actuate a control member 73 at the other end, the capstan 81 becoming coupled to a driven take-up hub 58 during the re-wind therefrom by a clutch responsive to the absence of tape on the hub. The control member 73 shown is a detent which locks a cover (30), Fig. 1 (not shown), in closed position over the supply reel 24, e.g. by an element 72 engaging an opening (71) in one hinge (67), the cover being unlocked only when tape has been entirely rewound on to the supply reel 24, permitting a spring-loaded pin 93 to open the cover. The transport motor may also be controlled to terminate playback. The capstan 81 and hub 58 are independently rotatable on a spindle 28, and the clutch comprises radial plates 80 on the hub which are held inwardly depressed against the force of a spring 83 by tape wound on the hub, a depending skirt 91 on the capstan 81 being accommodated in gaps 92 in the plates 80. The capstan is frictionally held against rotation by a spring wire loop 96. When tape has been unwound from the hub, at least one plate 80 moves outwardly, and plate portion 82 thereof engages one of a plurality of openings 89 in the skirt 91, so that the capstan 81 is driven. The transport is of the type wherein the peripheries of tape reels 24, 26 are biased against a reversibly-driven idler roller 22, the tape being tensioned by applying different biasing forces to the reels, Fig. 6 (not shown). An autothreading arrangement is also provided.

Cylinders, ports and liners of, covers for, and cooling.-The centre part 8 of a three-port liner for a double acting cylinder has scavenge-air inlet ports 1 with nozzles 2, which in alternate ports direct the air to opposite ends of the cylinder, and common exhaust ports 5. A casing 10, which is integral with the lower water jacket 9, is mounted on the bed-plate and the upper water jacket 11 is bolted to it or provided with lugs which are attached to extensions of the frame tie-rods; the jacket 11 clamps the centre part 8 of the liner in position. The outer parts of the liner are bolted to the centre part and free to expand at their outer ends. The piston nut 15 has the same diameter as the piston rod, and this causes the clearance spaces at the two ends to be similar annular chambers. Similar water-cooled heads are bolted to the jackets 9, 11, the piston rod gland being arranged outside the head. The Provisional Specification describes (1) a single row of inlet ports which coact with the side of the piston to direct the air to the cylinder ends, and (2) a liner which is constructed in one piece.

Class 37  To produce a barium titanate capacitor having an improved temperature/capacity characteristic the barium titanate dielectric is utilized in cubic crystal form and is given as a step in manufacture before firing a small content of foreign ions whose bivalent ionic radii are in the range from 0.6 to 1.0 Angstrom units and whose bivalent ionic potentials are in the range from 1.4 to 1.8. As representative materials fulfilling the ionic conditions the Specification mentions iron, nickel, cobalt, magnesium, calcium and manganese with preference towards iron and nickel. The Specification includes Fig. 3 to 8 (not shown), the characteristic curves which obtain with 0.1, 0.25, 0.342, 0.75, 1.0 and 2.5 parts iron to 100 parts BaTiO 3 . If nickel and magnesium are used the content should be in the range 0.3 to 1.00 parts to 100 parts BaTiO 3 . In all manufacturing example given FeO  3  is added to cubic BaTiO 3  in a beaker and stirred with water to produce a uniform suspension. The material is then dried and calcined at 1,100‹ C. for two hours. The calcine is then ground and mixed with 2 per cent. of an organic binder such as methyl cellulose in water and dried. The dried material is again ground and then pressed into discs or plates which are fired at 1,350‹ C. for two hours. To lower the dielectric constant inert materials, such as alumina and silica, may be added ; an example composition in this connection is made up of 4 parts silica and alumina to 100 parts barium titanate with iron addition or content.
